Simulation of natural Accommodation

The patented multi-aspheric design and aberration-reducing geometry of the PolyVue lens provides true monocular simultaneous correction for near, intermediate and distance vision while also simulating "natural accommodation" and reducing spherical aberration.

PolyVue -Unique Design

The PolyVue lens design consists of four zones of nonlinear multi-aspheric power progressions. The central zone is the patented "accommodation zone" which functions to simulate natural accommodation by creating a very small area of magnification approximately 25% to 100% over the near vision correction requirement. The accommodation zone is blended to the distance zone 4 via two zones of non constant aspherocity which allows monocular correction of near, intermediate and distant vision.

Aberration reduction geometry is also incorporated into the PolyVue lens to provide improved visual acuity as well as increased depth of field and consist sensitivity
